Fat people should be bluntly told that being fat is unhealthy and unattractive, not lied to with this "healthy at any weight" and "you're beautiful as you are" BS.
This modern "body positivity" stuff is insane and harmful and is one of the reasons fat people are everywhere nowadays. If everyone is too afraid to be blunt and lies to you, claiming you're healthy and hot, why would you lose weight? I'm not suggesting we randomly go up to obese strangers and call them fat pigs or anything, but back in my grandmother's day, you would be bluntly told you were getting fat and would struggle to find a good-looking partner etc. None of this insane woke "body positivity" nonsense. It's still like this in China, Japan, Korea etc and just like the 1950s West, they have very low obesity rates. And they didn't make up a million excuses why people were fat, they knew it was simply overeating and lack of exercise. Or gluttony and laziness, to be frank.
TLDR; Stop lying to fat people that they are healthy and beautiful, start shaming them again
